The +.rc for khtnmlpart (sorry, I never looked it up), doesn't +seem to provide much help. Also, to follow links, you +probably need to connect some signals to slots. I +haven't tried it, but this should work with a plain +KMainWindow or other widget too. + +The KDE website also incorporates gifs, jpegs, and +I believe CSS too.
